Physical Assessment of the Respiratory Tract III: Percussion01:29

Physical Assessment of the Respiratory Tract III: Percussion

The respiratory system, fundamental to life, consists of complex structures responsible for gas exchange. The percussion assessment is critical to understanding this system's health and functionality. This non-invasive assessment technique allows healthcare providers to evaluate the density or aeration of the lungs, thereby identifying potential abnormalities.

Mechanical Ventilation II: Invasive Ventilation01:23

Mechanical Ventilation II: Invasive Ventilation

Ventilators are essential medical equipment used to aid patients with respiratory difficulties. Their primary function is to assist or replace spontaneous breathing by providing mechanical ventilation. There are two general classes of mechanical ventilators: negative-pressure and positive-pressure ventilators.
Negative-Pressure Ventilators
Negative-pressure ventilators create a vacuum around the chest or body to draw air into the lungs, simulating breathing. This method does not require an...
Assessment of Respiration01:23

Assessment of Respiration

The respiratory system's basic structures and primary functions lay the foundation for nurses' comprehensive respiratory assessments. This assessment includes subjective and objective data to gauge the patient's respiratory health.
Subjective Assessment: Nurses interview the patient to gather information directly during the subjective assessment. It includes questions about the individual's medical history, medications, and symptoms, focusing on past respiratory conditions like asthma or COPD,...
Cardiopulmonary Resuscitation II: ACLS Airway Management01:22

Cardiopulmonary Resuscitation II: ACLS Airway Management

Airway management is a key skill in emergency and critical care settings, as maintaining a clear airway is essential for adequate oxygenation and ventilation.Head Tilt-Chin Lift TechniqueThe head tilt-chin lift maneuver is an essential technique primarily used in patients without suspected cervical spine injuries. To perform this maneuver, one hand is placed on the patient’s forehead, and gentle pressure is applied backward to tilt the head. The fingertips of the other hand are positioned under...
Assessment of Ventilation II: Respiratory Depth and Rhythm01:29

Assessment of Ventilation II: Respiratory Depth and Rhythm

Respiratory Depth
Respiratory depth measures the volume of air inhaled or exhaled during a breath. It can vary from shallow to deep and typically remains consistent when a person is at rest or asleep. Occasionally, individuals will automatically inhale deeply, known as sighing, which inflates the lungs with more air than normal breathing.
To assess respiratory depth, observe the degree of chest excursion or movement:
Ventilatory Modes01:14

Ventilatory Modes

Mechanical ventilators are life-saving devices that support or replace spontaneous breathing. They deliver breaths to patients through varying methods known as ventilator modes. Understanding these modes is critical for healthcare providers managing patients with respiratory failure.
There are three ventilatory modes: full support, partial support, and spontaneous. These are described below.
Full Support Modes
Full support modes include controlled mechanical ventilation, continuous mandatory...

Area of Science:

  • Medical Sciences
  • Aerospace Medicine
  • Critical Care

Background:

  • High-frequency percussive ventilation (HFPV) is a standard treatment for smoke inhalation injury.
  • Prehospital use of HFPV is limited by high medical gas requirements.
  • Military operations created a need for long-range aeromedical transport of burn patients.

Purpose of the Study:

  • To evaluate the feasibility of using HFPV for transcontinental aeromedical patient transport.
  • To assess the safety and efficacy of HFPV during long-distance flights on C-17 aircraft.

Main Methods:

  • Retrospective analysis of 33 burn patient transports using HFPV.
  • Utilized US Air Force C-17 aircraft with onboard medical oxygen supply.
  • Total transport distance of 174,145 air miles.

Main Results:

  • HFPV was successfully employed for aeromedical transportation of burn patients.
  • No adverse events related to HFPV use during transport were reported.
  • The C-17's integrated oxygen system facilitated HFPV use.

Conclusions:

  • HFPV is a safe and effective ventilation strategy for transcontinental aeromedical transport of burn patients.
  • The US Air Force C-17 aircraft is a suitable platform for HFPV deployment in critical care transport.
  • Experienced medical teams are crucial for successful HFPV implementation in flight.
